A change in attitude

On the car ride home, you notice her stealing glances at you, specifically at your crotch. That's the first time you've seen her do that. A minute or two later, she puts her hand on your knee. That's also new. She slides it slowly up your leg and reaches the inside of your thigh. At this point, she is staring right through your jeans. You've never witnessed her behaving like that, but you're certainly not going to complain. Her hand comes to a rest above your hardening member. She tries to grip it, but the fabric of your pants apparently doesn't let her do what she wants, because now, she slides her hand up your belly and tries to go under you belt. You don't really know what's happening, but you like it. At this point, you've reached your parking spot and you bring the car to a halt.

"What's gotten into you?", you ask her.

"Let's just go inside." There's a tone in her voice you don't recognize, but you follow it gladly.

As soon as you close the door of your apartment, she shows that she must have been holding herself back in the car. She's practically all over you, or rather your belt buckle and then your pants button and zipper. And then your boxers. And then, for the first time in about half an hour, she pauses as she takes in the object of her desire, having come to rest on her knees in that whole process. She seems almost in awe of what she beholds between your legs. Sure, it's a pretty decently sized dick at its about average 5.5", but nothing to write home about. Still, she seems oddly transfixed by it. She reaches for it with both hands. With a wide smile, she brings her head ever closer to it, closes her eyes, and gives the tip a kiss. You don't even know how to react. She's never given you that kind of attention without prompting.

Next, she starts gently exploring your tip with her tongue, her lips closed softly around it. Then, she takes it a bit further in, now fully enveloping the glans, and continues to swirl her tongue all around it sensually. After a few seconds of that, she starts gently stroking the shaft with her right hand, while letting her left hand wander around the back of your right knee and calf. It's a slow and steady rhythm she establishes and soon matches with her mouth. It is at this point that she turns her eyes up to your face, where your glances meet. Yours still somewhat bewildered by what's happening right now and hers fully devoted and filled with an eagerness you've never seen on her when she was giving you head. Consequently, that rhythm doesn't stay slow for too long. It is steady, though. Steadily accelerating, that is. You place your hands on her shoulders, wanting to interfere with her efforts as little as possible, but you can't help but add some movement of your own to the mix. You soon find a groove and move as one. You've been breathing heavier for some time already, but now, some pleasure-filled moans start escaping your lips. Again, you both start to speed up in your movements, driving you closer and closer to the edge, and then, you explode. Almost in ecstasy you release spurt after spurt of cum down her unusually appreciative throat. Greedily, she swallows all of it, making sure to clean you off with her tongue. Once she is finished, there is no trace of an ejection left on your penis, other than its gradual softening.

You slowly regain your composure. "Wow, that was amazing."

"I know" she simply replies, with a downright devious smile.

That's when she shows you some writing on her forearms you were too busy to notice before. On her left forearm, it says 'COCK HUNGRY', while on the right, she has written 'AMAZING AT GIVING HEAD'. One of the two is decidedly more readable than the other.

"Are you telling me that magic marker made you do this?"

"I told you magic is real. We just needed to find the right artifact."

"I guess so..." You can't wrap your head around this, but you feel more inclined to believe her. "But what if this was just a placebo thing. You just wrote those things down and that might have given you license and the confidence to act them out."

"In that case, we need another test. Something irrefutable..." After a few moments of thinking, she grabs something from her purse, turns around, lifts the hem of the back of her shirt with one hand and offers you the marker with the other. "Write something on me. I won't know what you've written. That way we'll know whether it works."
